@Frossion1996 Hi,
Im using this Sensor:
Temp2IoT
A little “build yourself” but the result is perfect. I’m using an iFrame to show it on my mirror.
With the Arduino IDE is was also able to adjust it a little bit to my belongings (transparent background and a little size adjustments).
This project is really amazing. In the summer I can directly see in the morning if I can jump directly into the pool.
Chris.
